The article cited does not support the claim that lifting weights makes you less athletic. The New York Times is a generally reliable source, though it is important to note that this article is centered around the personal experience of one athlete, and there are other opinions cited that contradict his own. The story itself is likely true as it has actual quotes and anecdotes from the people its referencing, though, the article does not claim that what works for one athlete will ring true for all. The claim stated here is inherently misleading.
